Pennsylvania Cinquefoil

Fireweed is a native perennial wildflower known for its tall spikes of bright pink to purple blooms. Its long-lasting summer flowers are an important nectar source for pollinators such as bees, butterflies, and hummingbirds, while its seeds provide food for birds. Its showy, long-lasting display makes it visually striking in naturalized plantings.

Fireweed gets its namesake because it is often one of the first species to return after wildfires, supporting ecosystem recovery. Its wind-dispersed seeds allow it to spread readily, making it highly effective in large-scale restoration, revegetation, and naturalization projects.
Fireweed is the Provincial Flower of the Yukon.

Pennsylvania Cinquefoil is well suited for naturalisation projects as it is a wildflower native to North America. It is widespread and can be found growing in rocky soils at higher elevations in the mountains and foothills, as well as the dry prairies. The Pennsylvania Cinquefoil is capable of growing in cold, harsh conditions. The bright yellow flowers are found at the top of long stalks in small dense clusters and are ideal for attracting pollinators.
